AbstractThe formation of density-tunable non–close-packed (ncp) monolayers of silica nanospheres via freeze drying is demonstrated. Monolayers of silica spheres with diameters of 120, 490, and 990 nm are achieved through a single-step freeze dry process. The densities of the spheres can be tuned by adjusting either the volume fraction of the spheres or the settling time before freezing. Issues involving defect-formation and defect-reduction are investigated. The experimental data suggest that this freeze drying method represents an efficient and robust way for achieving ncp monolayers of nanoparticles.
